Doc Text:
A flaw was found in FFmpeg. An attacker could exploit this vulnerability by supplying crafted audio files containing invalid Not-a-Number (NaN) floating-point samples to the native Vorbis encoder. This issue triggers an out-of-bounds memory read that can cause the application to crash, resulting in a Denial of Service (DoS), or potentially disclose adjacent memory contents.

Description OSIDB Bzimport 2026-11-10 19:42:43 UTC
FFmpeg before 8.1.3 and 9.x before 9.0.2 contains an out-of-bounds read vulnerability in put_vector() in libavcodec/vorbisenc.c when NaN samples leave the codebook entry at -1. Attackers can supply audio with NaN float samples to the native Vorbis encoder, causing heap reads before arrays that crash the application or leak adjacent heap memory into output.
